Abstract
The utility model discloses a thin high-sound-insulation floor board for a passenger compartment of a motor train, which comprises a composite layer and a mount. The composite layer is composed of multiple layers including a plywood board, a rubber pad, an aluminum honeycomb floor board, ultrafine glass wool and a steel floor board from top to bottom sequentially, damping grout is coated on both upper and lower surfaces of the steel floor board, the plywood board is isolated from the aluminum honeycomb floor board through the rubber pad which has a vibration absorbing function, the aluminum honeycomb floor board has fine sound insulation and heat insulation performances and higher vibration resistance, the ultrafine glass wool with fine sound absorption is added between the aluminum honeycomb floor board and the steel floor board and used as a sound insulation, heat insulation and vibration absorption material, and the damping grout coated on the inner and outer surfaces of the steel floor board has soundproof and heat-isolating effects. The floor board is simple in structure, convenient in installation and compact in structure, has better cold-proofing and heat insulation effects, realizes multi-stage buffer to vibration so as to achieves purposes of vibration adsorption and noise reduction. In addition, the total thickness of the floor board is about one third of that of a double-layer floor board, and accordingly space of the passenger compartment is saved greatly.
Description
Technical field
The utility model relates to a kind of motor-car guest room high Sound insulation floorings of thin layer.
Background technology
General domestic diesel coach set, its engine installation and auxiliary device thereof are arranged in below the car body underframe, during vehicle operating, the top in motor orientation (as the guest room part) vibration obviously, noise is also very big, so the floor, guest room is required to have performance-oriented sound insulation, heat insulation, effectiveness in vibration suppression, and structure must be compact.
Existing general floorings mainly comprises following a few class:
1, individual layer laminated wood floor
The individual layer floor panel structure is generally adopted on such floor, promptly (level land plate and corrugated floor) gone up and laid one deck laminated wood floor on the iron floor, the floor divides into shock pad, anti-skidding, the wear-resisting floor wearing floor leather of laying high-quality on the floor, individual layer laminated wood floor advantage is simple in structure, shortcoming is that sound insulation, effectiveness in vibration suppression are relatively poor, is mainly used on the main line railway passenger vehicle vehicle.
2, aluminium honeycomb floor
The individual layer floor panel structure is generally adopted on such floor, promptly (level land plate and corrugated floor) gone up and laid the layer of aluminum honeycomb floor on the iron floor, the floor divides into shock pad, anti-skidding, the wear-resisting floor wearing floor leather of laying high-quality on the floor, this floor advantage is simple in structure, sound insulation, effectiveness in vibration suppression are better, and shortcoming is the cost height, is mainly used on the railcar.
3, thick type double floor
Double floor is to increase one deck laminated wood floor on the basis of individual layer aluminium honeycomb floor, promptly be earlier on iron floor covering layers layer of aluminum honeycomb floor (the 2nd layer of floor), the centre adds aluminium and supports, hollow space filling winter protection material (superfine glass silk flosssilk wadding plate), on the 2nd layer of floor, lay one deck laminated wood floor (the 1st layer of floor) again, the middle aluminium beam that adopts hollow form, hollow space adds fills out the winter protection material, the floor gross thickness is 170mm, the double floor advantage is sound insulation, good damping result, shortcoming is a complex structure, and is more abundant, is mainly used on the diesel coach set vehicle.
The utility model content
The purpose of this utility model is the deficiency that overcomes above-mentioned general floorings, provide a kind of gross thickness only be double floor 1/3rd, but have the high Sound insulation floorings of thin layer of good sound insulation and noise reduction effect equally.
The purpose of this utility model realizes by following technical proposals:
A kind of motor-car guest room high Sound insulation floorings of thin layer, comprise composite bed and the mount pad be made up of multiple aspect, described composite bed comprises successively that from top to bottom laminated wood floor, rubber pad, aluminium honeycomb floor, super glass wool, upper and lower surface scribble the steel floor of damping slurry.
As optimal way: the thickness on described laminated wood floor is 10-30mm.
As optimal way: the thickness of described aluminium honeycomb floor is 17-27mm, and density is 6.5-7.5 kg/m2.
As optimal way: the thickness of the damping slurry of described steel floor upper and lower surface is 2-5mm.
As optimal way: described mount pad lower end and steel floor welding, is provided with wooden unit in the middle of the mount pad, be provided with the screw that connects rubber pad and aluminium honeycomb floor in the wooden unit.
As optimal way: described motor-car guest room is 47-67mm with the gross thickness of the high Sound insulation floorings of thin layer.
The beneficial effects of the utility model: the utility model the superiors are the laminated wood floor, this wood covering sound transmission loss has reached 31dB(A), separate with rubber pad with the aluminium honeycomb floor, play damping of vibrations, the thickness of aluminium honeycomb floor has only half of normal plywood, the aluminium honeycomb floor has good sound insulation, heat-proof quality, and in the honeycomb core of aluminium honeycomb floor, the solid material volume only is 1%～3%.Because honeycomb has many dense cellular that pin down mutually, just as many little H-girders, can disperse to bear the pressure from each side, therefore has stronger resistance to shock.Install the super glass wool with good sound-absorbing performance between aluminium honeycomb floor and the steel floor additional, as sound insulation, heat insulation, damping material, steel floor surfaces externally and internally spraying damping slurry plays sound insulation, heat-blocking action.This floor panel structure is simple, easy for installation, compact conformation, and well played winter protection, insulation effect, and multi-buffer has been played in vibration, noise has been realized multistage filtering, finally reached the purpose of vibration damping, noise reduction, and gross thickness only is about 1/3rd of a double floor, and the sound insulation and noise reduction effect is the same, has so just saved the space of guest room greatly.
